@bormolino I had exactly the same problem like you (also using the Nvidia 435 driver). For me it seemed strange because the folder /usr/src/linux-headers-5.4.0-42-generic DOES exist and also DOES contain both files include/generated/autoconf.h and include/config/auto.conf... Not sure why the error messages says these files can't be found. Do these files exist on your machine? Anyway, what solved my problem in the end was to upgrade to the latest nvidia driver 440 (I upgraded via the "Software & Updates" UI (under "Additional Drivers") (I guess it just installs the package nvidia-driver-440) I would guess what also would have solved the problem is to re-install the 435 driver (nvidia-driver-435)
